Biofuel made from rubbish and sewage

What do you get if you mix rubbish and sewage? Well apparently, quite a lot, a company, with the catchy name, Viridis waste control, Septage Bioreactor Landfill Technology, have just patented a new invention.

According to the patent, if you blend household rubbish and regular sewage, you will be able to cut greenhouse gas emissions, while at the same time supply clean water, and if that isn’t enough, a renewable, ‘green’ fuel for which there will be an endless supply of raw materials.

If left to their own devices, both raw sewage and rubbish just degrade, but as a side effect produce methane gas, a well documented source of large amounts of greenhouse gas. But apparently this process of decay, particularly in landfill rubbish, is very slow. So, production of this natural methane takes some considerable time.

The company claims that by blending together, they rubbish, and sewage, this vastly accelerates the breakdown of the household rubbish. The side effect of this rapid breakdown is quic,k, and plentiful, supplies of methane that can be used as fuel in its own right, or mixed with regular natural gas and piped to homes and businesses.

Other advantages of this quick mixing process are reasonably easy to imagine. Groundwater and surface water will be protected from pollution, pathogenic biological agents, produced in septic tanks, can also contaminate water sources, this process will eliminate that threat.
Instead of processing septic tank waste, to make it safe, it would be converted into fuel and not filtered back into the ecosystem.

Landfills will take several times longer to reach their maximum levels, as a lot of the waste would be diverted to create the new fuels.

If this new technology proves to be as viable as the company believes, this could be a worldwide, eco-friendly, waste disposal revolution.
